Note: The heat index, also known as 'feels like' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
